1080p g-sync monitor for a reasonable price

[Rexbeer]

I'm looking for a 1080p monitor that has g-sync already installed. i would like it to be around 300-400$ USD. i also would like it to be 120-144hz with a 1-3ms response time for gaming. if you believe that i could get something better for a little bit more money, please recommend it to me. i already have a build. any recommendations please go ahead and comment.

You already have a VFM monitor selected.

And just in case you want to go to choose ASUS VG248QE as i have already suggested above. It would be amiss to mention a better option than Asus @ $50-60 additional :

Benq XL2430T is a much newer monitor than the VG248QE. The VG248QE has been out for awhile now and has seen no new iteration/replacement from ASUS, whereas the XL24xxT series has seen several iterations (2410, 2420, now 2430..) from BenQ to improve the process.
